    Abstract The generation of chimeric antigen receptor-modified natural killer (CAR-NK) cells using induced pluripotent stem cells (iPSCs) has emerged as one of the paradigms for manufacturing off-the-shelf universal immunotherapy. However, there are still some challenges in enhancing the potency, safety, and multiple actions of CAR-NK cells. Here, iPSCs were site-specifically integrated at the ribosomal DNA (rDNA) locus with interleukin 24 (IL24) and CD19-specific chimeric antigen receptor (CAR19), and successfully differentiated into iPSC-derived NK (iNK) cells, followed by expansion using magnetic beads in vitro. Compared with the CAR19-iNK cells, IL24 armored CAR19-iNK (CAR19-IL24-iNK) cells showed higher cytotoxic capacity and amplification ability in vitro and inhibited tumor progression more effectively with better survival in a B-cell acute lymphoblastic leukaemia (B-ALL) (Nalm-6 (Luc1))-bearing mouse model. Interestingly, RNA-sequencing analysis showed that IL24 may enhance iNK cell function through nuclear factor kappa B (NFκB) pathway-related genes while exerting a direct effect on tumor cells. This study proved the feasibility and potential of combining IL24 with CAR-iNK cell therapy, suggesting a novel and promising off-the-shelf immunotherapy strategy.

    Abstract The impairment of cognitive function was considered as a major clinic feature in Alzheimer's disease (AD) patients. Thus, a number of researches related to AD were focused on the changes in brain. However, as a neurodegenerative disorder with systemic inflammation, the periphery organs may also play a key role in AD pathology. Here, we pose the hypothesis that histopathology and inflammatory response of periphery organs may alter with aging in APP/PS1 mouse model. Therefore, we performed immunohistochemical staining technology to double label Aβ plaques and microglia cells in brain. The H&E staining was performed in periphery tissues and the mRNA expression of inflammatory factors IL-6, IL-10 and TNF-α were also determined. Next, the index of oxidative stress was measured. Consequently, the level of inflammatory factors was significantly increased in 24 months APP/PS1 mice. Furthermore, the enzyme activity of SOD, CAT and GSH were significantly decreased in colon and other organs. Our results demonstrated the increased inflammation response and declined antioxidative capacity of periphery organs in aged APP/PS1 mice, which suggesting that a more comprehensive perspective to study AD were necessary.

    Abstract Seeds play a crucial role in plant reproduction, making it essential to identify genes that affect seed development. In this study, we focused on UDP-glucosyltransferase 71C4 (UGT71C4) in cotton, a member of the glycosyltransferase family that shapes seed width, length, and therefore, seed index and seed cotton yield. Overexpression of UGT71C4 results in seed enlargement due to its glycosyltransferase activity on flavonoids, which redirects metabolic flux from lignin to flavonoid metabolism. This shift promotes cell proliferation of ovule via accumulation of flavonoid glycoside, significantly enhancing seed cotton yield with the seed index increasing from 10.66 g to 11.91 g. In contrast, knockout of UGT71C4 leads to smaller seeds owing to activation of the lignin metabolism pathway, and redirection of metabolic flux back to lignin synthesis. This redirection leads to increased ectopic lignin deposition in the ovule, inhibiting ovule growth and development, and alters yield component, increasing the lint percentage from 41.42% to 43.40% but reducing the seed index from 10.66 g to 8.60 g. Our research sheds new light on seed size development and opens potential pathways for enhancing plant seed yield.

    Abstract Background: Plants differ more than threefold in seed oil contents (SOCs). Soybean (Glycine max), cotton (Gossypium hirsutum), rapeseed (Brassica napus), and sesame (Sesamum indicum) are four important oil crops with markedly different SOCs and fatty acid compositions.
    Results: Compared to grain crops like maize and rice, expanded acyl-lipid metabolism genes and relatively higher expression levels of genes involved in seed oil synthesis (SOS) in the oil crops contributed to the oil accumulation in seeds. Here, we conducted comparative transcriptomics on oil crops with two different SOC materials. In common, DIHYDROLIPOAMIDE DEHYDROGENASE, STEAROYL-ACYL CARRIER PROTEIN DESATURASE, PHOSPHOLIPID:DIACYLGLYCEROL ACYLTRANSFERASE, and oil-body protein genes were both differentially expressed between the high- and low-oil materials of each crop. By comparing functional components of SOS networks, we found that the strong correlations between genes in "glycolysis/gluconeogenesis" and "fatty acid synthesis" were conserved in both grain and oil crops, with PYRUVATE KINASE being the common factor affecting starch and lipid accumulation. Network alignment also found a conserved clique among oil crops affecting seed oil accumulation, which has been validated in Arabidopsis. Differently, secondary and protein metabolism affected oil synthesis to different degrees in different crops, and high SOC was due to less competition of the same precursors. The comparison of Arabidopsis mutants and wild type showed that CINNAMYL ALCOHOL DEHYDROGENASE 9, the conserved regulator we identified, was a factor resulting in different relative contents of lignins to oil in seeds. The interconnection of lipids and proteins was common but in different ways among crops, which partly led to differential oil production.
    Conclusions: This study goes beyond the observations made in studies of individual species to provide new insights into which genes and networks may be fundamental to seed oil accumulation from a multispecies perspective.

    Abstract Simplex identification via split augmented Lagrangian (SISAL) is a popularly-used algorithm in blind unmixing of hyperspectral images. Developed by Jos\'{e} M. Bioucas-Dias in 2009, the algorithm is fundamentally relevant to tackling simplex-structured matrix factorization, and by extension, non-negative matrix factorization, which have many applications under their umbrellas. In this article, we revisit SISAL and provide new meanings to this quintessential algorithm. The formulation of SISAL was motivated from a geometric perspective, with no noise. We show that SISAL can be explained as an approximation scheme from a probabilistic simplex component analysis framework, which is statistical and is principally more powerful in accommodating the presence of noise. The algorithm for SISAL was designed based on a successive convex approximation method, with a focus on practical utility. It was not known, by analyses, whether the SISAL algorithm has any kind of guarantee of convergence to a stationary point. By establishing associations between the SISAL algorithm and a line-search-based proximal gradient method, we confirm that SISAL can indeed guarantee convergence to a stationary point. Our re-explanation of SISAL also reveals new formulations and algorithms. The performance of these new possibilities is demonstrated by numerical experiments.

    Abstract Objectives: Clinical data with respect to the impact of meconium on the prognosis of neonatal bacterial meningitis are scarce. Therefore, in this study, we aimed to determine whether meconium-stained amniotic fluid (MSAF) represents a risk factor for poor prognosis of neonatal bacterial meningitis in a confirmed case population.
    Methods: This was a retrospective cohort study of 256 neonates diagnosed with bacterial meningitis hospitalized at one of three hospitals in Shantou, China, between October 2013 and September 2018. Clinical manifestation, laboratory test results and treatment were compared between the two groups, with outcomes dichotomized into 'good' or 'poor' prognosis. Multivariate analysis and follow-up logistic regression analysis were used to identify predictive factors of a poor outcome.
    Results: Of the 256 neonates with BM, 95 (37.1%) had a good prognosis at discharge and 161 (62.9%) had a poor prognosis. In the poor prognosis group, 131/161 (79.4%) neonates had a permanent neurological sequelae and 19 (11.8%) had ≥2 sequelae. Of note, 11 neonates died. The rate of poor prognosis of BM was significantly higher among neonates with than without MSAF (26.1% vs. 12.6%, respectively; p < 0.05). A logistic multivariate analysis to evaluate the prognostic effect of MSAF to BM showed that neonatal with MSAF is more likely to have a worse prognosis of BM [unadjusted odds ratio (OR), 2.44, 95% confidence interval (CI), 1.24-5.10; adjusted OR, 2.31; 95% CI, 1.09-5.17].
    Conclusion: MSAF is significantly associated with poor prognosis of neonatal bacterial meningitis. Therefore, in case of MSAF, more attention should be paid to neonatal bacterial meningitis.

    Abstract Introduction: Allotetraploid upland cotton (Gossypium hirsutum L.) is native to the Mesoamerican and Caribbean regions, had been improved in the southern United States by the mid-eighteenth century, was then dispersed worldwide. However, a Hainan Island Native Cotton (HIC) has long been grown extensively on Hainan Island, China.
    Objectives: Explore HIC's evolutionary relationship and genomic diversity with other tetraploid cottons, its origin and whether it was used for YAZHOUBU (Yazhou cloth, World Intangible Cultural Heritage) weaving, and the role of structural variations (SVs) in upland cotton domestication.
    Methods: We assembled a high-quality genome of one HIC plant. We performed phylogenetic analysis, divergence time estimation, principal component analysis and population differentiation estimation using cotton assemblies and/or resequencing data. SVs were detected by whole-genome comparison. A F
    Results: We found that the HIC belongs to G. purpurascens. G. purpurascens is best classified as a primitive race of G. hirsutum. The potential for long range transoceanic dispersal of G. purpurascens seeds was proved. A set of SVs, selective sweep regions between G. hirsutum races and cultivars, and quantitative trait loci (QTLs) of eleven agronomic traits were obtained. SVs, especially large-scale SVs, were found to have important effects on cotton domestication and improvement. Of them, eight large-scale inversions strongly associated with yield and fiber quality have probably undergone artificial selection in domestication.
    Conclusion: G. purpurascens including HIC is a primitive race of G. hirsutum, probably disperse to Hainan from Central America by floating on ocean currents, may have been partly domesticated, planted and was likely used for YAZHOUBU weaving in Hainan much earlier than the Pre-Columbian period. SV plays an important role in cotton domestication and improvement.

    Abstract The growth of plant roots is regulated by various factors. Brassinosteroids (BRs) can induce asymmetric root growth (ARG) to form waves and coils, and this phenomenon can be eliminated by ethylene (ETH) inhibitors aminoacetic acid (AOA) or silver thiosulfate (STS), indicating this process depends on ETH pathway. Nevertheless, the research on related genes has not been reported. In this study, four treatments (Water, Brassinolide (BL), BL + AOA, and BL + STS) were set up using the seedlings of Oryza sativa as materials. The differentially expressed genes (DEGs) in BR-induced ARG via ETH pathway were identified by transcriptome sequencing, weighted gene co-expression network analysis (WGCNA), and real-time quantitative PCR (qRT-PCR). Finally, we screened 70 DEGs, including ALPHA-EXPANSINs (OsEXPAs), WALL-ASSOCIATED RECEPTOR KINASE-LIKE 16 (OsWAKL16), and TRANSMEMBRANE KINASE (OsTMK) that regulated cell elongation and expansion, as well as plant hormone synthase genes, 1-AMINO-CYCLOPROPANE-1-CARBOXYLIC ACID OXIDASEs (OsACOs), OsYUCCAs, and CYTOKININ OXIDASE(OsCKX). Most of them were up-regulated by BRs via ETH pathway. In addition, the receptor-like kinase (RLK) gene ROOT MEADNDER CURLING (OsRMC), a negative regulator in jasmonic acid-induced ARG, could be inhibited by BRs, and this process also depended on ETH pathway. The identification of the above genes provides evidence for revealing the molecular mechanism in the process.

    Abstract A simple and rapid sensing strategy was proposed for chloramphenicol (CAP) detection based on structure-switching signaling aptamers. In this protocol, the aptamer can bind to both the fluorophore (FAM)-labeled complementary strand and the quencher (BHQ1)-labeled complementary strand, thus leading to the effective quenching of FAM fluorescence by BHQ1. However, when CAP is present, the structure switch is reversed because the aptamer recognizes CAP, resulting in fluorescence recovery. Such a fluorescence-sensing platform can monitor CAP within a good linear range (1 to 100 ng/ mL), with a detection limit of 0.70 ng/mL. Cross-reactivity with other common antibiotics is negligible, indicating the excellent selectivity of the strategy. Moreover, as the aptamers are not modified, this method is simple and low-cost. The present work reveals a new direction for detecting CAP or other target compounds without prior knowledge of the secondary or tertiary structures of the aptamer.
